Getting Started with Angular: An Introductory Guide 🚀

1. What is Angular? 🤔

Angular is a TypeScript-based web application framework created by Google. Known for its scalability and robust tooling, Angular is a popular choice among businesses, but not always as popular with hobbyists and individual developers. As the author, even I find it a bit too opinionated for personal projects due to its strong conventions and structured approach, which can feel restrictive. However, this lack of freedom actually benefits companies by maintaining a consistent and predictable codebase, making it easier to scale and manage large applications.

As the Angular documentation states, everything in Angular revolves around components—reusable, modular UI elements that make your code easy to maintain and extend. With Angular’s built-in tools, you can handle everything from routing and state management to forms and HTTP requests in a highly structured and efficient way.

2. Why Use Angular? 🤷‍♀️

Why Choose Angular Over Vanilla JavaScript, HTML, and CSS?

While HTML, CSS, and JavaScript are essential for creating web applications, they lack a structured approach for organizing and managing complex codebases. Angular provides a component-based architecture that simplifies this process by breaking down your app into isolated, reusable pieces.

The main reason for using any JavaScript framework, including Angular, is that raw JavaScript can quickly become difficult to manage as a project grows. It’s challenging to keep code maintainable, and working in a team without a framework can lead to inconsistencies and confusion. Angular’s architecture and tooling solve these issues by enforcing patterns that make development easier and more predictable, especially in a team setting.

There’s also a factor of “victory bias” in Angular’s popularity. Companies have had success with Angular, so others follow suit, even if it’s not clear if Angular is objectively the best choice for every use case. This momentum keeps Angular a key player in the business world.

Why Choose Angular Over React?

React is another popular option, and it’s more flexible and widely used by individual developers and startups. So why would you choose Angular over React?

• Opinionated Framework: Angular provides a well-defined structure out of the box, whereas React is more flexible, allowing developers to integrate whatever tools and patterns they prefer. Angular’s structure may feel restrictive, but it simplifies decision-making, especially in large teams.

• TypeScript by Default: Angular’s native support for TypeScript enables strong typing, improved error handling, and better tooling. While React can also be used with TypeScript, Angular’s built-in support reduces the need for extra configuration.

• Comprehensive CLI: The Angular CLI covers everything from testing and production builds to linting and deployment. React’s CLI offers fewer built-in features, making Angular a more complete solution for enterprise-level applications.

In summary, if you’re building a large, structured application or working with a big team, Angular’s conventions can save you time and reduce complexity. React, on the other hand, is better suited to projects where flexibility is prioritized over strict patterns.

3. How to Get Started 🚀

If you’re ready to try Angular, here’s how to set up your first project.

Step 1: Install Angular CLI

Angular CLI (Command Line Interface) simplifies project setup and automates common tasks. To install it, use npm:

npm install -g @angular/cli

Step 2: Create Your First Angular Application

With Angular CLI installed, create a new project:

ng new my-first-angular-app

Follow the prompts to choose options like routing and stylesheet format. Once the project setup is complete, navigate into your new project directory:

cd my-first-angular-app

Step 3: Run the Application

To view your Angular app, run:

ng serve

Then open http://localhost:4200 in your browser to see the default Angular welcome page!
